Seismic Response Analysis Of The Deepwater Tank

Our country is a nation with high-frequency earthquakes, many liquid filled vessels may be damaged during earthquake. This will bring serious secondary disasters and economic loss, so it is meaningful to analyze its seismic dynamic response and seismic behavior to adopt necessary engineering measures to reduce its direct and secondary disasters.At present, the seismic analysis of liquid filled vessels is based on some simplified methods. Though some finite element numerical analysis has been performed before, it is hard to be widely applied in engineering because of the limitation of its functions and scales. In this thesis, the large-scale general finite element analysis software ANSYS is applied in numerical simulation and seismic response of the deepwater tank in Shanghai Jiaotong University.Researches in huge reinforced concrete deepwater tanks are rare, in which the constitutive relationship of materials of tanks is considered as linear. In the thesis, a combination between the strain-stress curve of steel bar and concrete is applied to take the non-linearity of materials into consideration. Considering the interaction between water and tank, the FLUID80 and SHELL63 elements in ANSYS are used. Firstly, analysis of...
